Magnetic Microspheres

Superparamagnetic particles have been utilized extensively in diagnostics and other research applications for the purification of cells and biomolecules, such as antibodies, nucleic acids, and polypeptides. They confer a number of benefits, including ease of separation and suitability for automation. When coated with recognition molecules, magnetic microspheres are ideal for the efficient capture and separation of target. Unwanted sample constituents may be washed away following a simple magnetic separation step.

Our different superparamagnetic microparticle product lines allow us to uniquely address a wide range of applications in the life sciences, from cell separations and immunoassays to suspension arrays and flow cytometry.

Magnefy™

Meet the newest addition to our family of magnetic particles–Magnefy™ ~1µm carboxylated superparamagnetic microspheres. As high surface area / high surface titer microparticles with a rapid separation profile, Magnefy offer an additional performance-driven solid phase for magnetic particle-based assays and isolations, particularly SPRI-based total DNA isolation. Contact us today to explore using Magnefy as your OEM SPRI bead.

ProMag® HP

ProMag® HP (High Performance) have been meticulously engineered for use in assay development. The highly optimized composition ensures lowest autosignal, particularly with respect to chemiluminescence and exposed iron.

COMPEL™

COMPEL™ are highly uniform superparamagnetic microspheres ideal for applications that demand uniform particle response. COMPEL™ are comprised of iron oxide crystals dispersed in a polymer matrix, with a functional polymer overcoating for the encapsulation of magnetite and the introduction of reactive groups. As they are polymer-based, they retain the low density that is advantageous for biomolecular assays. Our offerings include 3µm, 6µm, and 8µm beads with measured CVs of ≤ 5% and high levels of COOH-functionalization.
